why don't you try to migrate the forums and consolidate into one and then serve it from a single instance.
Thanks for the reply Hoque.
Migration of the forums can be thought of as an option, but would like to avoid it when already there is one instance available with the forums.
Migrating the forums from an already existing forum to the default one that comes with the webcenter installation will be a round about task isn't it.
Thats why wanted to check if there is a possible way to directly integrate with existing jive instance.
If you are using webcenter portals' forum taskflows,then I would say. Its better to migrate because forum retrieval is done by Oracle not by jive. In my opinion, oracle has somehow modified forum services altough it is completely based on jive library. But still as of now,either you modify forum retrieval process otherwise migrate it.
Hope you understand my point.
Best of luck,
